Federal investigators have concluded that the man responsible for a mass shooting at Brown University and the subsequent murder of a Massachusetts Institute of Technology professor did not act at random. Instead, they believe he deliberately targeted places and individuals that held symbolic meaning, representing his personal failures and perceived injustices.
FBI Behavioral Assessment Released
In a detailed behavioral assessment released on Wednesday, the FBI identified the gunman as Claudio Neves Valente, 48, a former Brown student and Portuguese national. According to the report, Valente spent years planning the attack in isolation before killing two students and wounding nine others inside an engineering building on December 13. Two days later, he killed MIT professor Nuno F.G. Loureiro at his home in Brookline, Massachusetts. Valente was later found dead from an apparent self-inflicted gunshot wound inside a storage facility in Salem, New Hampshire, ending a multistate manhunt.
Pattern of Isolation and Grievance
The FBI described Valente as a man who lived in isolation for years, rarely staying in one place and lacking traditional support systems such as family, peers, or authority figures who might have recognized warning signs and alerted law enforcement. Over time, investigators said, he constructed a narrative of grievance and inadequacy, with "little to no opportunity for bystanders to observe and contextualize the significance of his behaviors."
"He appeared to struggle with how he viewed his life achievements and felt he was considerably marginalized by others," the FBI wrote in the report. "As his failures outweighed successes, his paranoia increased, compounding his continued inability to thrive and leading to him being mentally unwell and committed to dying."
Symbolic Nature of Violence
Authorities emphasized that the violence itself was "symbolic in nature." Brown University and Professor Loureiro, investigators wrote, represented to the shooter "his personal failures and injustices he perceived were inflicted by others over time." By attacking them, Valente was likely able to overcome his shame and envy, using violence to punish those communities he believed contributed to his downfall. However, the FBI acknowledged the limits of their analysis, noting that only Valente himself knew the full reasons behind the attacks and that mental health stressors alone cannot fully explain them.
Post-Attack Recordings and Legal Proceedings
After the attacks, investigators said Valente recorded videos and audio messages in which he confessed to the shootings, expressed no remorse, and voiced some of the grievances later outlined in the FBI's assessment, but offered no clear explanation for his actions. Investigators have stated that Valente acted alone and that the attacks had no known connection to terrorism.
Authorities also revealed that Valente briefly attended Brown as a doctoral student in the early 2000s but did not complete the program, a connection that investigators believe factored into how he viewed the university. The firearms used in the attacks were legally purchased in Florida years earlier.
The findings come as students injured in the attack filed a lawsuit earlier this week, alleging that the university ignored prior warnings about the shooter and did not provide adequate security that could have prevented the tragedy.
